Doctors have replaced the cancer-stricken windpipe of a patient with an organ made in a lab, a landmark achievement for regenerative medicine. The patient no longer has cancer and is expected to have a normal life expectancy, doctors said. "He was condemned to die," said Paolo Macchiarini, a professor of regenerative surgery who carried out the procedure at Sweden's Karolinska University Hospital. "We now plan to discharge him [Friday]." The transplantation of an entirely synthetic and permanent windpipe had never been successfully done before the June 9 procedure. The researchers haven't yet published the details in a scientific journal.
